I. Teeth— Ache, Decay, Piling— Wolf Teeth. 

 Causes- — Derangements of the teeth very frequently lead to jrravc 

 difficuhit's, both local and constitutional. The teeth often heconi'e 

 decayed, holes form in them, and tooth-ache is a common occurrence. 



How to know it. — It will be detected b}^ the horse holding his head 

 on one side \vhile chewing, turning his head first one way then the other, 

 as if trying to remove food from a sore tooth, 

 and doing th(; same when drinking, if the water 

 is very cold. The disease often extends up the 

 tooth, or starts in the form of ulceration on the 

 fang, and breaks out into the nose, causing a 

 discharge from the nostril on the side on which 

 the rotten tooth is located. A chronic discharge 

 from a tooth is often mistaken for nasal gleet,

 disagreeable odor, which will be recognized as that characteristic of dis- 

 eased bone. 



Sometimes the ulceration, when of a lower tooth, breaks out at tne 

 angle of the lower jaw, and sometimes extends to the root of the tongue 

 and to all the soft tissues between the ])ranches of the lower jaw ; in one 

 instance that came under the notice of the writer, the disease proved fatal 

 to a Yaiuable horse. 



The teeth frequently get broken b}^ chewing on stones taken up with 

 oats, and when one molar tooth gets broken off, the opposite tooth, not 

 having anything to wear against, gets very long and sticks into the oppo- 

 site gum, and makes mastication very painful. The edges of the molar 

 teeth get sharp from the fact that they wear bevelling — the edges must 

 necessarily sharpen as they wear ; the upper rows bevel downwards and 

 outwards, the edges cutting the cheeks, and the lower rows bevel upwards 

 and inwards, cutting the tongue.
